When you extract parameters into the Master parameter set then the only way to see where the Master came from is in the Parameter Definitions form. You can get to this form 3 ways. The pull down menu labeled Edit has Parameter Definitions in it. The toolbar is the second way. The third way is to populate the grid from a parameter set with Parameter Properties. If you double click in the grid then you can also pull up this form on the first record in the table.
The bottom 3 fields are Server, Project and Job names of where this parameter was originally extracted from.
